Digital Payment Scheme
A payment scheme is a set of rules and technical standards for the execution of
payment transactions that are followed by adhering entities (payment processors,
payers and payees). A digital payment scheme is one where transactions take place
over digital networks (such as the Web). Some digital payment schemes make use
internally of payment instruments from other payment schemes. How they register and
communicate with internal payment instruments is beyond the scope of this charter.
